If your 23 year old is/was a full-time college student in 2020 you get the $500 credit for other dependents AND you are the one who can claim the education credits on your own tax return if you claim her as a dependent. If you itemize deductions then any out of pocket medical expenses you paid for your dependent can be entered.
If she graduated in 2020 and has begun earning money then you need to determine if you have paid for over half her support in 2020 -- it's tricky in the year of graduation.
